Huh. So if Senshi was just a kid by dwarven standards when he first got into the dungeon at 36 and just some 10 years passed since then, doesn't that mean he's still awfully young? Probably younger than Laius in relative terms.
@Anrhaa I've rechecked and Senshi himself said that he's been researching monster cuisine in the dungeon for "over ten years", which should be more or less the time he spent in the dungeon. And in this chapter he says explicitly that the town above and the dungeon became connected "before long". Over ten years, but still not as long ago as I would've assumed from the set-up.
